Top congressional investigators from both parties vowed Friday to expand their respective investigations into the IRS targeting scandal, with one leading House investigator suggesting the Obama administration had a role in the scandal and slapping down claims that the IRS’ misconduct was not planned and coordinated.

“We’re going to get the truth and we’re going to hold people accountable,” said Republican Rep. Dave Camp, chairman of the House Ways and Means Committee, which along with Rep. Darrell Issa’s Oversight Committee is one of the two House committees investigating the IRS for its improper targeting of conservative groups and individuals between 2010 and 2012.

“The IRS is part of the [Obama] administration,” Camp said at a newsmaker breakfast Friday hosted by The Christian Science Monitor. “There is a lot more work to do.”
